Abstract: PARACHUTE WITH CANOPY OPENING ASSIST AND OPENING CONTROL         Abstract of the Disclosure The parachute opening assist and control arrangement is a small auxiliary canopy in combination with a series of transverse reefing lines.  The auxiliary canopy is folded within the main canopy and is connected to the reefing lines.          Each reefing line is connected between two opposed main support lines.  When the parachute is fully open, the reefing lines are a series of transverse lines which cross each other at a central point.  The ends of the reefing lines are connected to the main support lines at a point close to the skirt of the main canopy.  The auxiliary canopy extends above the reefing lines.  A positioning line is connected between the crown of the main canopy and the center point of the reefing lines.          The positioning line may be foreshortened to increase the reefing effect during canopy opening. The auxiliary canopy and reefing lines together increase the speed of initial opening and control the opening to reduce the maximum shock during opening.                        - i -

Abstract: ABSTRACT OF THE DISCLOSURE     An insulator for clamping and holding an electrical con-ductor above the ground for aerial power distribution and trans-mission including a body, a first jaw integral with one end of the body, a slide, a second jaw integral with the slide and a mounting for the slide in the end of the body for longitudinal movement substantially normal to the first jaw.  It also includes a bolt for causing movement of the second jaw towards the first jaw for gripping a conductor between the jaws.  The disclosure is also directed to a method of stringing an electrical conductor on a plurality of insulators which are supported above the ground on a series of poles.  The method utilizes a plurality of string-ing devices each of which comprises two semi-tubular members detachably secured together to provide a circular passage between them.  The conductor is pulled through a series of stringing devices which are held between the generally concave surfaces of the insulator bodies and generally concave surfaces of jaws on slides of the insulators.  The conductor is then tensioned.  Then the stringing devices are removed from the conductor by sliding them longitudinally of the conductor and separating the semi-tubular members.  Then the jaws of the insulator are closed to grip the conductor.

Abstract: ABSTRACT             A tape cassette recording and/or playback apparatus with a device for changing the drive when a component, comprising a drive member and actuating member, which rotates only during tape transport is stationary.  The drive members performs a rotary movement, taking the form of an eccentric, and is adapted to cooperate with a pivotably journalled lever.  The lever is connected to the component via a friction coupling, which during rotation of the component exerts a torque on the lever and keeps it positioned against the drive member so that the lever performs a swinging movement when the component rotates and is set to a stationary position by the drive member when the component is stationary.  The actuating member performs a periodic movement from which the stop or over operation for the tape drive can be derived by the actuation of a switching device via the actuating member when the lever is in the stationary position.  The drive member can be driven by a first wheel and actuating member by a second wheel and the actuating member is constituted by a connecting rod which is eccentrically and pivotably journalled on the second wheel and is articulated to the lever via a coupl-ing rod.  The coupling rod transmits the swinging movement of the lever also to the actuating member and in the stationary position of the lever moves the actuating member to a position from which, during its reciprocating movement, it actuates the switching device.

Abstract: ABSTRACT OF THE DISCLOSURE     A multiple groove pulley is formed from a cup-shaped blank by an apparatus and method in which axially displaceable segmental shaping rings are positioned at axially predetermined positions along the wall of the blank.  Fluid pressure communicated to the interior of the blank expands the wall of the blank into contact with the shaping rings and at least one of the shaping rings is independently movable in an axial direction while the blank is compressed for simultaneous formation of the grooves.          A sleeve member is movable axially over at least one of the shaping rings to resist radial movement of the segments while at the same time permitting full compression of the blank.

Abstract: ABSTRACT OF THE DISCLOSURE    Fibrous casing is manufactured wherein a paper tube is passed downwardly over a mandrel and impregnated with viscose. The interior and exterior sidewalls of the tube are contacted with a coagulating liquid to regenerate cellulose on the tube walls.  Spent coagulating liquid is withdrawn from the tube interior by the imposition of a pressure differential on the liquid.  Withdrawal of the liquid also causes the walls of the descending tube to be drawn into disadvantageous wiping contact with the mandrel surface.  This wiping contact is reduced or substantially eliminated by introducing a gas, e.g., air, at a low positive pressure, into the spent liquid being withdrawn from the tube to form a fluid mixture having a specific gravity less than that of the liquid.

Abstract: ABSTRACT OF THE DISCLOSURE Process for preparing an electrophotographic element comprising an electrically conductive support and a photoconductive layer comprising a film-forming polymeric binder and a photosensitive azo-compound, in which process the photosensitive azo-compound is synthesized in situ in the film-forming polymeric layer on the support by reaction between a diazonium compound and an azo-coupling component.  The azo-compounds thus synthesized are distributed in the binder layer, in an almost homogeneously perfect form.  Under a scan-ning electron microscope they are no longer distinguishable as separate par-ticles, not even at a ten thousand fold magnification.  The invention also relates to an electrophotographic element prepared according to such a process. Such elements are useful in various types of electrophotographic copying methods.

Abstract: ABSTRACT In the selection of a signal using a narrow band pass filter, a tracking type band pass filter is usually employed in order not to cause a phase difference between input and output even if the input frequency changes. However, this tracking type band pass filter generates a delay time for the transitionary input signal since a feedback control is used.  In the present invention, therefore, the input signal is divided into two parallel routes and they are combined again by a multiplier, and phase difference between input and output is successfully isolated from the effect of frequency by inserting band pass filters or delay lines and frequency multipliers or dividers   This is achieved by making the frequency ratio of the two routes equal to the total sum of the group delay times from input to output.
